1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Background: Managing ischemic cardiomyopathy-related ventricular tachycardia (VT) remains clinically challenging since no definitive consensus exists regarding the optimal therapeutic approach. Therefore, this study aimed to assess the safety and efficacy of catheter ablation for VT in patients with ischemic cardiomyopathy. Methods: We systematically searched the PubMed, EMBASE, and Cochrane Library databases to identify pertinent clinical trials. We selected the relative risk (RR) and mean difference (MD) as the effect measures, which were calculated using Review Manager software. Additionally, we used trial sequential analysis to assess each outcome. Results: Our study included six randomized controlled trials with 1064 patients. Catheter ablation was found to reduce the risk of the composite endpoint (RR 0.83, 95% confidence interval (CI) 0.74-0.94; Conclusions: Catheter ablation reduced the incidence of composite endpoints, cardiac hospitalizations, and adverse events related to VT in patients with ischemic cardiomyopathy. However, no statistically significant differences were found between the two groups for VT recurrence, appropriate ICD shocks, and all-cause mortality.
